AJCA Database Update for Jersey-Cross Prefix Underway
February 5, 2017

On Saturday, February 4, 2017, the American Jersey Cattle Association will update the animal database to implement the Jersey-Cross (JX) prefix.

By direction of the AJCA Board of Directors, the JX prefix will be added to the recorded name of any animal that has one or more ancestors of another breed within six (6) generations. The prefix will be dropped after six (6) generations. The Board’s action was announced in the December 2016 issue of Jersey Journal.

An animal’s Generation Count is not changed by the addition of a JX prefix. Generation Count refers to the number of generations of an animal’s known and AJCA-recorded ancestors. Animals that have seven (7) or more unbroken generations of recorded Jersey ancestors do not have a Generation Count suffix. If less than seven, the number in brackets indicating the number of generations recorded appears as a suffix in the AJCA registration name.

The infoJersey website will be taken offline at 8:00 a.m. EST on Saturday, February 4, with completion targeted for 5:00 p.m. the same day. When infoJersey service is restored, the JX updates will immediately be in online queries, AJCA documents and in BullsEye. Reports published as part of Green Book Online will be updated after the February monthly genomic evaluation release on February 7.
